Lilo seems to have moved on from Sam and is dating model Adam Senn! She has already took him home to meet her mother Dina and her siblings, and it seems that things are getting serious even though this blind item just surfaced:

Which male model is regretting he got carried away with a certain starlet? He succumbed to her aggressive seduction, didn’t use protection and now worries he may have contracted an STD.

There is no other starlet dating a model (except Kelly-O but she's been a while with him and they're engaged) so it seems it's about Linds! What a Christmas gift she has given him!
